not to sure if OCing the ram is what a highly OC'd cpu can deal with. Simply having highly overclockable ram (high frequency) gives someone the head room to OC the cpu more. If anything people tend to drop the ram settings to stabilize a high OC... I have; in the past, water cooled ram and it was beneficial to stabilizing the cpu and squeezing a little more outta the cpu. While water cooling the ram has been debated over the years I had to try for myself and see and discovered it did help more than not.

Are you planning to maintain a heavy OC or is it just for testing/fun. Do you maintain a lower OC regularly?
